Learning Aligned Cross-Modal Representations from Weakly Aligned Data

People can recognize scenes across many different modalities beyond natural images. In this paper, we investigate how to learn cross-modal scene representations that transfer across modalities. To study this problem, we introduce a new cross-modal scene dataset. While convolutional neural networks can categorize cross-modal scenes well, they also learn an intermediate representation not aligned across modalities, which is undesirable for cross-modal transfer applications. We present methods to regularize cross-modal convolutional neural networks so that they have a shared representation that is agnostic of the modality. Our experiments suggest that our scene representation can help transfer representations across modalities for retrieval. Moreover, our visualizations suggest that units emerge in the shared representation that tend to activate on consistent concepts independently of the modality.Comment: Conference paper at CVPR 201

Hovering-mode control of the glider-type unmanned underwater vehicle

Thesis (Master)--Izmir Institute of Technology, Mechanical Engineering, Izmir, 2011Includes bibliographical references (leaves: 104-107)Text in English; Abstract: Turkish and Englishxiii, 109 leavesResearch on the underwater robotics has attracted the interest of many researchers over the years. The primary reasons are the need to perform underwater intervention tasks that are dangerous for a diver and the need to perform underwater survey tasks that last for longer periods of time. Unmanned underwater vehicles can be divided into two categories. Most of the systems, today, that require a certain level of precision and dexterity are built as Remotely Operated Vehicles (ROV). On the other hand, the systems that perform repetitive tasks are configured as Autonomous Underwater Vehicles (AUV). The objective of the thesis is to design a novel, cost-efficient, and fault-tolerant ROV that can hover and be used for shallow water investigation. In order to reduce the cost, the numbers of thrusters are minimized and internal actuators are used for steering the vehicle and stability in hovering mode. Also, the design is planned to be open for modification for further improvements that will enable the use of the vehicle for intervention tasks and studies. In this work, previously developed unmanned underwater vehicles are reviewed. Following this, the conceptual designs are created for the underwater vehicle and internal actuator designs are developed. Designed mechanisms are modeled in SolidWorks© and transferred to MATLAB© Simulink for hovering-mode control studies. Afterwards, to verify the simulation results, experiments are conducted with a seesaw mechanism by using LabVIEW© programming. Finally, results are given, discussed and future works are addressed

Investigating prospective primary teachers' pedagogical content knowledge of "effect of human on environment" subject in the process of teaching practice

CALIK, MUAMMER/0000-0001-8323-8783;WOS: 000321397400013The principal aim of this study is to determine what the extent of the prospective primary teachers' (PPT) pedagogical content knowledge (PCK) is on "effect of human on environment" subject in grade 5 science and technology curriculum before and after "Teaching Practice" course. Within case study research methodology, the study sample consisted of 6 senior PPTs selected from 49 trainees who attended "Teaching Practice-II" course in spring semester of 2009-2010 schooling year in the programme of primary teacher education in Rize University. To collect data, lesson plans, observations, and semi-structured interviews were used. While the data obtained from lesson plans and observations were analyzed by means of rubrics developed, those from semi-structured interviews were analyzed using content analysis. It was found that the PPTs did not have sufficient idea of sub-components of the PCK, especially curriculum knowledge, and knowledge of students' learning difficulties. Nevertheless, it was determined that the PPTs had adequate idea of pedagogical knowledge in context of the PCK. However, it was drawn out that although they had sufficient theoretical knowledge about instructional methods, techniques, strategies, measurement and assessment, they encountered some problems in transferring the theoretical knowledge into practicum. in the light of the results, it is suggested that the PPTs should be given more opportunities for practicing complementary measurement-assessment techniques. Furthermore, it is recommended that the PPTs with their own lesson plans ought to be given more opportunities to transfer their PCK into related subject matter one

Capire la Turchia al di là dei Pregiudizi

Turkey's recent foreign policy orientation has both been lauded and criticized. While some analysts argue that Turkey is on the way to become a regional power through its «multi-stakeholder» foreign policies, others suggest that the country is now sliding away from its EU membership course and pro-Western policy choices towards the «Islamic» camp, especially considering the recent tension with Israel and divergence from US's policy on Iran. This article aims to provide a more balanced picture through an examination of Turkey's history of domestic politics and foreign policy
